I was recently searching for photos of the Niagara online when I discovered
that there was a star painted on the top of the capstan. I decided this was
the perfect excuse to rework the capstan. In the process I discovered that
by applying slope to my textures, I could show wear on the edges of the
parts. I rendered this image with poor radiosity settings, but was so
pleased with the results of my texture experiments, that I decided to share
them with you. the star is a prism that is set into the black wood. All of
the textures are procedural.
Now I need to finish reworking the bottom half of the capstan and
then....rework all the wood textures using slope....this project was
originally concieved as s short project I could use to learn POV-Ray....I
am learning, but it is not a short project!
As allways, I love criticism,
Tim

So -that's- what slope maps are for... Looks nice, Tim. Maybe as you rework
the wood textures, make it the wood a wee bit rougher?

I find the textures with the worn edges extremely impressive ! Do you 
mind showing an example of your slope texture ?

You really freak me out with all this detailed ship building stuff. I just 
watch it being put together, when you post updates, but figured I could stop 
and say something for a change...
Did you realize the boards don't have a gap all the way through? The 
greenish circular part, I mean, not the deck.
Yeah, I must find fault or I don't feel complete.  : )
BTW, any plans to animate a walk-through on and around the S.S. Niagara? Or 
is this very slow to render?

I hope being freaked out is a good thing!

The gap is there, but very small. These boards are supposed to be butted up
against each other. I am attaching an image close up showing the fine seem
between them.

:) I would like to get a little further ahead to create an animation. i
think I will also build a web page for the entire project.
thanks for you comments Bob.

Thank you for your comments. I appreciate it. Here is a sample of the
texture.
#macro WornWood(RGB,WearFlat,WearEdge,Norm,Rot,Tran)
        #declare Texture1 =
                texture {
                        pigment {

                            scale <0.15, .5, 1>
                            rotate <5, 10, 5>
                            translate -x*2

That's some fantastic carpentry. I could use such skill IRL instead of the 
haphazard way I go about it. I like how this view remains good even though 
so close now.
